This paper investigates the effect of a Virtual Reality Flight Simulator (VRFS) on pilots’ performance and workload while flying visual circuit patterns. The aim of this research is to compare and quantify the difference between this novel simulation environment and well-known and widely used hardware simulators. A general aviation simulator that serves as a baseline was recreated in the virtual environment. The experimental evaluation was conducted with 28 pilots who performed two traffic patterns in each environment. In virtual reality most participants were able to safely and reliably complete the flight task after a short acclimatization phase. The results allow quantifying the degradation of performance metrics and the increase of workload in the virtual environment. The results will be used for future research with the virtual reality flight simulation.
